This was not so much annoying but incredibly funny nonetheless...
Co-worker decided to bring his somewhat large dog into the office. Needless to say, the dog was excited and tremendously nervous.
Thus, the dog felt the urge to do its business and snap off a deuce right in the main hallway. Best part...my co-worker didn't notice for like 10 minutes...the pile just sat there while people nearly stepped in it.
When he finally realized what had happened, he cleaned it up...only to throw it away in the men's room trash. Not outside, or flush it...the trash where it stunk to high heaven the rest of the day.
And somehow we still have "bring your pet to work day" here.
But I actually love where I work, everyone is pretty cool.
